Awesome gym. Beginner, intermediate, advanced; they have it all. Unlimited classes and gym time for one easy payment a month. Easy and no excuses to stay in shape or learn a new technique/sport!

The coaches & students are amazing. Everyone is extremely knowledgeable & helpful, including front desk associates. 10/10 would recommend.

I love X3! From the moment I was introduced to this fitness family and went on a tour of the gym, I was hooked! Dwayne is a phenomenal trainer and has helped me improve my technique over the years! His kickboxing classes are my favorite— action packed and FUN filled! The management and team at X3 is built of incredible and kind individuals, and the value of the membership is well worth the cost!

X3 North Marietta has been my sanity saver since I started in July 2020. When I joined, the GM told me that most people end up wanting to come in almost everyday of the week but I had my doubts. Now, I go as many times a week as I possibly can and even spent my birthday doing PT and Muay Thai class. All the coaches are great but I really like working with Dwayne and Johnny - they are fantastic coaches and have become my friends as well! I love that they have kids classes too - my 5 year old does youth boxing and BJJ while I do kickboxing so it works out wonderfully.

I’ve been working out here for almost 2 years. Everyone is great to train with especially Dwayne and Nandi.

A fun and motivating place to get real results! I love X3 and highly recommend it for anyone wanting to find a smaller gym where you can be challenged and motivated. I’ve been coming here for years now and it’s like my second family. The trainers are great and the have a number of different types of classes available. Be prepared to sweat and have a great time while doing it!

Talk about feeling at home! My son has been taking the 6pm boxing class and every participant has helped grow his confidence and skills. He’s getting stronger abs better daily! I would highly recommend for anyone interested in the sport!

I love the variety of classes (Boxing, Jui JItsu, Muay Thai and Kickboxing). The instructors are awesome.

All the trainers and staff at X3 are professional, polite, and they know their stuff. Whether you train casually like myself or are looking to go pro, they are able to help. They are also clean people; which is always good.

Jay and the instructors working with my son have been so kind, patient, and compassionate.

The staff is experienced and extremely helpful. I feel like I learn a lot every single time I go.

Amazing staff and trainers! No matter your fitness level or experience, X3 trainers and members are friendly and engaging. Everyone is treated like an athlete...not just someone taking a class.

Love this gym! The trainers are phenomenal, and they do a great job of keeping the gym clean, which is a big deal. Our entire family goes a few times a week, and it has a great family environment for all ages.

I’ve been wanting to try kickboxing for a while now and I am so grateful that I found X3! I love the North Marietta location. It was really easy to get to from 75, it’s super bright and clean, and Robert the GM is very professional and welcoming. My kickboxing class with Brandon was everything I expected and more! He’s a true trainer, focused on making sure you get the most out of your workout and that you are using the proper technique to ensure effectiveness and safety. Highly recommend!!!

Great first experience. Johnny knows his stuff.

I learned a lot about Muay Thai in this gym and enjoy kickboxing. 😁

This place will STEAL YOUR MONEY. I paid off the remainder of my contract and they continue charging me monthly for dues IVE ALREADY PAID. They guaranteed me that I would not be charged again and I keep getting charged. They are thieves. Ive spoken to them and they are not interested in helping. Theyre even rude about me wanting to stop getting double charged. I want a full refund.

The instructor was very good at making corrections when they were necessary and otherwise being encouraging from a distance once my form was right. The space was very bright and open. The equipment was clean and organized. All of the things Ive grown accustom to from X3 but in another convenient location outside of the perimeter.

This is the best gym Ive ever been apart of . best staff and everyone is super friendly I love it here

It’s a great atmosphere for both an average workout or intense fight training. I lost over 40 pounds this past year, and I even fought in a amateur kickboxing event. The coaches and classes provide a fun atmosphere to challenge myself and my teammates. -Hunter C.

I took kickboxing and weight training classes here from Feb to July and lost 40 lbs. Would recommend 10/10 very good program. Take Byrons classes he is an excellent instructor.

I came here for as a guest for an hour and yeah I definitely want to come back. The trainers and staff are all very professional and work with you in a very engaging way and want to see you progress. Id highly reccomend to anyone!

By far one of the best gyms- everything from the trainers to the members to the location. Excellent workout (kickboxing) with a wide selection of classes and times to choose from. I love everything about this place

Im a new member of this location and honestly it was the best time Ive had at a fitness center in a years. The kickboxing, fast track and muay thai classes are taught by trained and talented instructors who care about your progress. The community vibe is second to none, I felt a true sense of belonging. I highly recommend X3 Sports!

Great experience at X3. I wanted to better myself and this place is passing expectations. Keep up the great work!

The trainers, facility, and location are all top notch. The schedule is diverse and has plenty of options no matter when you are looking to workout and offers a variety of different program types.

I do boxing there it is alot of fun i have made some freinds. consider doing ju jujitsu later its awesome best place iv trained at

Update 1/30/2019 - Emailed the club as asked in response to my review and received help. My issue was is now resolved. Thank youAccount administration is handled through a 3rd party (ABC Financial). I had a concern that I brought to ABC Financial regarding cancellation. Long story short ABC Financial gave me some bad information..

Good place to get back in shape. Better than wondering around aimlessly at Planet Fitness trying to act like you know what youre doing.

I love this place. They truly care about your results! Byron is the best!

Awesome location, people, and workout classes! Check out Byron or Traviss kickboxing class for a challenging (but fun) workout!

It’s a family there, you get to know people and you help each other and push each other to surpass their limit, we all become a family.

Instructors are superb and there is literally a class for everybody

Great location, great gym, great trainers and overall amazing workout.

Great gym atmosphere, great coaches and awesome people.

A must for any martial artist regardless of discipline, get a membership for any number of reasons, far to many to list but engagement and knowledge of their craft is what sold me.

Great gym I repeat GREAT GYM

Love it.

LOVE THIS PLACE!
